Neon sea creatures have been captured lighting up the ocean with their vibrant colors – in what looked like a scene from Avatar. Photographer Simon Pierce, 39, took the images over several months after visiting both Nosy Sakatia in Madagascar and Mafia Island in Tanzania recently. (Photo by Simon Pierce/Caters News Agency)

Brave photographer Masa Ushioda captured the shots of this wild gator in vast marsh land in the Everglades National Park, in Florida, USA. He said: “Bright sunlight and blue sky were critical elements in this picture – in addition to getting a wild 10-foot alligator in the middle of the viewfinder with a perfect angle”.

Japanese businessman Kiyoshi Kimura has paid 1.38 million euros ($1.76 million, or 155.4 million yen) for a blue fin tuna – more than three times the previous high – which he also set one year ago. The 222-kilogram fish will be served to Kimura’s customers. Blue fin tuna is annually sold in a traditional New Year’s auction. Japan consumes 80 percent blue fin tuna caught worldwide.

The holder of half a dozen world records will walk across the Grand Canyon on a steel cable with nothing but the Little Colorado River 1,500 feet below on June 23. With no tethers or safety nets, the walk will be the highest tightrope attempt ever for the 34-year-old, at a height taller than the Empire State Building. Last year, Wallenda, a seventh-generation member of the “Flying Wallendas” family of acrobats, became the only person to walk a wire over the brink of Niagara Falls.

When you first see the art works created by a Thai metalworker Ban Hun Lek, you are completely stunned by the level of detail of the metal sculptures that he creates. One of his most prominent creations is a full sized sculpture of a Hulk. The fact that this sculpture was created practically solely out of steel nuts adds to the rugged feeling of force that emanates from this creation. And if you think that this creation is amazing, you should look at his other works such as the Ganesha – the god of wisdom, knowledge and new beginnings, or the Predator. For that matter, almost every sculpture that he creates blows your mind away, making you wonder just how many hours has he put into making these amazing pieces of art. (Photo by BanHunLek)

Vanessa Silva, 38, feeds macaws that fly to her apartment window every day looking for food, in Caracas, Venezuela, on November 24, 2014. A group of gold-and-royal blue birds poked their heads through Silva’s window, as if saying “I’m here, is anyone home?” “I’d seen them flying when I was down on the street, and I thought ‘Oh how pretty,’” the 38-year-old said, a macaw eating out of her hand.
